I have heard reloaders like on Gun Tec TV say bullets can be too long for the twist or too short, my barrel is 26 inches long with a 9 1/2 twist ..
my question is doesl anyone know the perfect bullet grain for this twist
I would think the grouping would indicate this... I am using 139 Hornady...
I have the RCBS manual trimmer and works fine but if in a hurry I use the Lee setup with the wooden handle ball its premeasured and you don't have to stop and make sure the RCBS is set right, just a few turns with your hand and its done...also very cheap
